Andrej Karpathy built a better YouTube in 2 hours
This is a dev post classified by AGK Intelligence as AI dev tools (a tool drop), kept by the Dev Radar because it carries real work, not commentary.
Andrej Karpathy built a better YouTube in 2 hours without writing code. Karpathy turned 19 years of Hacker News comments into a full YouTube clone entirely by using Opus 5.5. He didn’t write a single line of code. Claude Opus did the scraping, filtering, UI, deployment, and security. HackerTube now serves 6,454 high-signal videos pulled from 19 years of Hacker News recommendations. - /karpathy.bearblog.dev/hacker-tube/
